One example from my D1, 1/1000 sec ISO 200, probably f/2.8? Taken just below the summit of Old Man of Coniston, blowing a gale, we had just abandoned the attempt to the top. The wind was so strong I couldn't stand up, I lay flat on my stomach with elbows dug into ground trying to keep the D1 still. It took several attempts to get a steady shot of the outcrop.

The second taken at the explorers garden Pitlochry, PH16 5DR. D3, 1/640 Sec f/5.6, ISO 1600.

This is my best guess also...at least for the very first 105mm from the rangefinder times, considering the short supply and great expense of computing power in those days. If their initial calculations had hit 110mm as an unusually optimized design spec, they might have all been One-Tens for all these years!It is equally possible in my mind that as Nikon's success mounted over the years, that the company seized upon the 'One-O-Five' as a symbol of corporate identity in the marketplace, and thereafter deliberately designed all of its 100mm-class lenses to have this identifying characteristic.

It was more about lens speed according to this article: https://en.wikipedia.org/wiki/History_of_photographic_lens_designThe first 105mm lens may have been the Ernemann Ernostar 10.5cm f/1.8 of 1924.We are seeing this speed seeking tradition continue in lenses like the recent 105mm f/1.4 lenses that happen to be quite sharp as well.
